Updated to 8.0.1482 this morning. So far all ok on Windows XP P4 @ 1.8Ghz and 512MB RAM
I do not use the browser plug-ins and I check for updates myself to most programs.
The new interface is somewhat "Bland" ... we need a couple of skins to pick from.
Also the update did not carry over my Exclusions List .. I had to redo them manually.
Otherwise, it seems fine.
